The father of the leaders of the pro-Islamic State Maute group that seized control of a southern Philippine town in May died while in government custody, authorities said on Sunday.
Cayamora Maute was taken to a hospital on Sunday afternoon after his blood pressure rose but he died along the way, the Philippines' prison bureau said.
The May 23 occupation of Marawi City by the Maute group, led by his two sons and which has pledged allegiance to Islamic State, triggered a brutal urban battle with military forces that entered its fourth month last week.
